EXTENSlB hE-PQST BINDER;

SPECIFIGATION formingpart of- Letters PatentNo.'730, 318, dated JuheQ, 1903- I Application filed October I4 1901,, Serial No. 78,565- (Homodoh) T0 ctZZ whom it may concern:

Be it known that I, FRED 1V. TOBEY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Expansible-Post Binders," of which the following is a full, clear, and ex act description, reference being bad to the accompanying drawings, forming part of this specification.

My invention relates to that class of binding files composed of a base forming one cover of the file, from which two posts ex tend up at right angles from the base near one end thereof to receive the perforated papers which are filed thereon and a top piece forming the other cover of the file and provided with perforations to enable it to he slipped over the posts and to become locked thereto to hold the papers securely between the two covers, while at the same time the top cover can be removed whenever it is desired to add new papers or to take out old papers, and said top cover also has a flexible joint near the posts to permit it to be opened and closed like the back of a book to inspect the contents of the file at any time. Heretofore these post-binders have usually had long posts extending considerably above the top cover, even when the binder was partially or nearly filled, thus rendering the binder unsightly and objectionable as a piece of office furniture, for the double reason that articles would come in contactwith the posts to disturb the position of the binder, and again for the reason that another hinder or other article could not be placed upon it after the manner of piling up books.

The object of my present invention is to provide posts for this class of binders which shall be telescopic and expausible to enable the posts to project as little as possible from the top ofthe binder-cover and at the same time to enable the inner or male members of the posts to be interchangeable from time to time when drawn out to their farthest limit by substituting longer members therefor.

It also has for its object the improved construction of the binder by which its simplicity, cheapness, and efficiency of action are secured.

'of-i-Fig. 2 looking to the right.

The novelty of my invention will be hereinafter more fully set forth, and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a sectional side elevation of a binder emhodyingmyinvention on the dotted line a; a: Fig. 2 is an end elevationof the binder looking to the left of Fig. 1. Fig. 3 is a broken sectional elevation corresponding to Fig. l and showing the upper post extended. Fig. 4 is an enlarged perspective view of one of the post guide and locking plates. Fig. 5 is a top plan View of the same. Figs. 6 and 7 are detailelevations of two of the extension-posts.

The same letters of reference are used to indicate identical parts in all the figures.

A represents the rectangular base of the binder, having secured to it at one end and projecting therefrom at right angles two tubular posts B, which are interiorly threaded. These posts 13 are comparativelyshort and receive upon them the perforated sheets which are to be filed.

D is the top cover, preferably provided with a hinge-joint a, Figsrl and 3, and with an extension D, with perforations registering with the posts B, so that the cover can he slipped over the posts B.

Covering each of the perforations in the extension D of the cover D is a metal plate E, Figs. 4 and 5, suitably secured to said extension, in this instance by rivets b, Fig. 2, through perforations c and having a depression or gutter (1, through which extends a perforation c for the passage of the post. The gutters in the plates E are at right angles to the top edge or upper ends of the filed pa-.'

pers and extension D, and the edges of the perforations e are on diderent levels, those at the upper or outer side being. lower than those of the inner or lower side, as clearly indicated in Figs. 1 and 3. By this construc- Ice When the posts B are filled or nearly filled with filed papers 0, as in Figs. 1 and 2, ex-

tensible screw-posts F, having their upper ends bent into gooseneck or crank form f, are screwed into the posts B, as shown in said figures, with the bent portions f standing toward the upper edges of the cover and papers, so that the perforations e in the plates E can readily pass over said bent portions in removing or replacing the top cover, as will be readily understood. By gradually screwing up the posts F the filing-space is increased and additional papers can be filed directly upon the posts F, as seen in Fig. 3, thus greatly increasing the filing capacity of the binder, and when thus screwed up the bent portions fare turned inward after the top cover has been applied, as seen in Fig. 3, to form a lock with the plates E to hold the top cover in place, as will be readily understood. By having a number of screwposts of different and increasing lengths, as F F Figs. 6 and 7, the capacity of the binder is'still further increased, each longer ting into and engaging the posts B and provided at their upper ends with bends f, the top cover D and-the perforated plates E secured to said topcover and adapted to fit over and be locked by the screw-posts F, substantially as described.
